To install and use an Expert Advisor on MT5, follow these steps:
Download the EA file (usually ending in .ex5 or .mq5).
- Open the MT5 platform.
- From the top menu, click File → Open Data Folder.
- In the new window, go to MQL5 → Experts.
- Copy your EA file into the Experts folder.
- Close and restart MT5 so it recognises the new EA.
- In MT5, open the Navigator window (press Ctrl+N).
- Expand the Expert Advisors list - you should now see your EA.
- Drag and drop the EA onto a chart of the instrument you want to trade.
- A settings window will appear; adjust the inputs as needed, then click OK.
- Make sure Algo Trading (green button on the toolbar) is enabled.
